Well, the heating season has started here in western Mass. I have had my Newmac burning wood for a week now, and after last year, I am feeling pretty good about what I'm seeing so far. Last year, we were building our house, and got caught offguard with heating. we had to purchase firewood from wherever we could get it. This resulted in burning wet, green wood all winter. I was burning a TON of wood, and I was running my air intake wide open all the time. This year, I was able to cut my own wood all summer (about 9 cords). So we are heating with dry, seasoned wood. I am now able to close the intake down to the minimum, and run up to 12 hours before reloading the firebox. There is minimal smoke, and minimal creosote (unlike last year). Now I am actually getting to "know" my heating system, and I'm loving the fact that it is soooo much more efficient now. I just hope that 9 cords gets me through the season.
